1. Summary:
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Real Time (v. 8) - x86_64 Red Hat Enterprise Linux Real Time for NFV (v. 8) - x86_64
3. Description:
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: insufficient input validation in kernel mode driver in Intel i915 graphics leads to privilege escalation (CVE-2019-11085)
* kernel: DMA attack using peripheral devices (Thunderclap) (BZ#1690716)
* kernel: infinite loop in update_blocked_averages() in kernel/sched/fair.c leading to denial of service (CVE-2018-20784)
* kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS (CVE-2019-11810)
* kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* kernel-rt: update to the RHEL8.0.z batch#2 source tree (BZ#1717516)
4. Solution:
